The religious revival that flourished in the early nineteenth century and changed American life found its most spectacular expression in Rochester, New York. The revival, in Rochester and elsewhere, made the United States the most militantly Protestant nation on earth and had an enormous influence on many Northern antebellum reform movements, including abolition and temperance. But although many historians have discussed its profound and wide-ranging effects, we know very little about its causes. "A Shopkeeper's Millennium" not only explores the interconnections between these vitally important economic, social, political, and religious changes but presents an evocative picture of a rapidly growing frontier city.
